Panzerschreck (German:
tank shocker) was the popular name for the Raketenpanzerbьchse
('rocket tank rifle', abbreviated to RPzB), an 88 mmcalibre
reusable anti-tank
rocket launcher developed by the Germans
in World
War II. Another popular nickname was Ofenrohr ("stove
pipe").[1]

It was given to infantry
to bolster their anti-tank capability. The weapon was shoulder-launched and
fired a rocket-propelled, fin-stabilized grenade
with a shaped
chargewarhead.
It was made in much smaller numbers than the highly successful Panzerfaust,
which was a disposable recoilless
rifle firing an anti-tank warhead.
